Help: time(0) crash/freeze

[DannyBackx]

Hi,

I'm still trying to determine why my code freezes at times.
A log of this morning's crash shows :

I (66541022) Peers: ImageFromPeerBinaryAsync 192.168.0.199 23457

I (66576242) Peers: QueryPeers 961
I (66576242) Peers: QueryPeers 973

The last two lines are from this piece of code. I've indicated the line numbers mentioned in the log.

Code: Select all

void Peers::QueryPeers() {
  ESP_LOGI(peer_tag, "%s %d", __FUNCTION__, __LINE__);  // <-- this is line 961
  // Protect against nearly infinite loops
  if (lastqp == 0) {
    // We'll fall through, so launch an initial query
    lastqp = time(0);

    if (lastqp == 0) {          // Complexity because time(0) initially returns time since boot
      // Make sure to do this initial query just once
      lastqp = 1;
    }
    ESP_LOGI(peer_tag, "%s %d, lastqp = %ld, do query", __FUNCTION__, __LINE__, lastqp);
  } else {
    ESP_LOGI(peer_tag, "%s %d", __FUNCTION__, __LINE__);  // <-- this is line 973
    time_t now = time(0);               // Crash ??
    ESP_LOGI(peer_tag, "%s %d", __FUNCTION__, __LINE__);
    if (lastqp == 1) {
      ESP_LOGI(peer_tag, "QueryPeers lastqp == 1 -> return");
      return;
    }
    ESP_LOGI(peer_tag, "%s %d", __FUNCTION__, __LINE__);

This appears to indicate that the time(0) call freezes.

Help, anyone ?

Thanks,

Danny
